Movie 2.

Confocal timelapse experiment (maximum intensity projection) of a crx:GFP transgenic embryo from 60 hpf to 72 hpf, with a temporal resolution of 10 min. During this time, the imaged cells at the apicalmost region of the retina display the extension and retraction of tangential processes. Scale bar: 5 μm. See Fig. 4A for further reference.
